Introduction
Protein-energy malnutrition (PEM) remains a critical global health concern, particularly in clinical settings where effective management is pivotal for positive patient outcomes.The prevalence of PEM, characterized by inadequate intake of protein and calories, necessitates a comprehensive understanding of diverse therapeutic approaches.In the seminal work by Kulkarni et al, [1] the authors underscore the significance of tailored interventions to address the complex etiology of PEM, emphasizing the need for personalized strategies based on the severity and underlying causes.
Building on this foundation, recent studies by Ubesie et al [2] and Pan et al [3] have highlighted the multifaceted nature of PEM management, emphasizing the role of nutritional rehabilitation, pharmacotherapy, and psychosocial support.Smith's exploration of innovative nutritional interventions underscores the potential benefits of incorporating specialized dietary regimens. [2]eanwhile, Brown's investigation delves into the integration of pharmacological agents, shedding light on emerging therapies that aim to augment conventional nutritional approaches. [3]his case report contributes to the existing literature by offering a nuanced comparative analysis of distinct therapeutic modalities employed in managing PEM within a clinical setting.The integration of findings from landmark studies [1] and recent advancements [2,3] forms the basis for evaluating the efficacy and limitations of different interventions, providing valuable insights for optimizing patient care.
